Just as a follow-up, I replaced my leaking wheel cylinder seal with the extra slave cylinder seal that I had. The hole is a bit smaller, as Curtis said, but it slid on with no extra effort and rotated freely on the piston. I pressurized the system overnight and I've got probably 10 hours of driving time on it now with multiple hard braking tests with no leaking. This was on my 1969 SRL with a 3/4" slave cylinder and 3/4" wheel cylinders.

What happened with the Moss Motors 3/4 kits, didn't wind up buying them?

Anyone try the Moss Motors 3/4 kits? If so did they work on 3/4 cylinders?

The dust boot on the Moss kit, 99% chance it won't work, but the piston seal is the key component. No idea about that one. I have a few OEM. Message me if interested.

Thanks for all the input. Datsun Roadster Parts.com is backed up and not taking orders for awhile. Does anyone else have any ideas on a substitution piston cup for 3/4" Roadster wheel cylinders?
